17‐epi‐Melianodiol, a new protolimonoid from Melia azedarach fruits, exhibits larvicidal activity and is associated with oxidative imbalance and midgut epithelial damage in Aedes aegypti larvae

Pest Management Science, Volume 82, Issue 9, Page 9240-9248, September 2026.
The bio‐guided phytochemical study resulted in the new compound 17‐epi‐melianodiol. The compound eliminated 100% of Aedes aegypti larvae at 100 ppm, causing pronounced morphological changes, cuticular damage, and extensive vacuolization. Abstract BACKGROUND In Brazil, Aedes aegypti is the primary vector of arboviruses such as dengue, chikungunya ...

Decoding chemical profiles in insect‐induced gall development: Insights from Phacopteron lentiginosum–Garuga pinnata interactions

Entomological Science, Volume 29, Issue 3, September 2026.
Analysis of volatile and non‐volatile metabolites across three developmental stages (3rd, 4th and 5th instar nymphal stages) of leaf galls induced by Phacopteron lentiginosum on Garuga pinnata revealed that the 3rd stage exhibited the highest chemical diversity and concentration followed by 4th and 5th stages.

The ApHSF–ApCtf1β2–ApCUT3 Cascade Couples Host ROS Detoxification to Cuticle Penetration During Fungal Pathogenesis

Molecular Plant Pathology, Volume 27, Issue 9, September 2026.
The ApHSF–ApCtf1β2–ApCUT3 transcriptional cascade links fungal adaptation to host‐derived ROS with cuticle penetration during infection. ApHSF promotes ROS detoxification and activates ApCtf1β2, which induces ApCUT3 expression and cuticle degradation, thereby coordinating oxidative stress adaptation with host barrier penetration.

Harnessing two UDP‐glycosyltransferases from Saponaria officinalis toward heterologous production of endosomal escape enhancer saponins in Gypsophila elegans hairy roots

The Plant Journal, Volume 127, Issue 6, September 2026.
SUMMARY Soapwort (Saponaria officinalis) synthesizes a vast repertoire of specialized metabolites with bioactive properties. Among those, a specific type of highly glycosylated oleanane‐derived triterpenoid saponins has potential applications in the pharmaceutical industry due to their anticancer activity and enhancement of endosomal escape for ...

Characterization of functional metabolites in broccoli by‐product using green extraction with supercritical fluids

Journal of the Science of Food and Agriculture, Volume 106, Issue 11, Page 6789-6799, 30 August 2026.
Abstract BACKGROUND The present study aimed to valorize broccoli by‐products (leaves and stems) through the extraction of bioactive compounds using supercritical fluid extraction (SFE). The influence of broccoli variety, plant part and maturation stage on total phenolic content (TPC), antioxidant activity and antimicrobial properties was evaluated ...
